> Any idea on what could be changed?Possibiltiies which occur to me include: * Store the thumbnails in a tmpfs. If we had encrypted swap (which we really ought to have anyway) then that would pretty much solve the privacy problem with not too much loss of performance. * Store the thumbnails in the same directory as the images themselves (and automatically prune old thumbnails). This has much better privacy properties but it may not be trivial to do on non-sane filesystems. Another problem is that removeable flash media (often used for image storage) tend to be rather slow and also wear out faster if you make `unnecessary' writes. * Encrypt each thumbnail with a key derived from the full file contents. This would need some careful design (of both crypto and surrounding machinery).
